The problem with Tesla's "No LIDAR ever, cameras are good enough" approach is that it fails to detect emergency vehicles: they filter out stationary items out of radar signal as noise[1],and Tesla's ML models probably can't reliably identify oblique vehicles and semi trailers as obstacles.

1. Makes sense in isolation: frequent radar returns from roadside and overhead signs would be a pain to deal with

Probably an artifact of the older versions.

See the Tesla AI Day. I expect the new stuff to deal with this a lot better.

What is the reasoning behind "no lidar"? Cost?
The stated reason is "your eyes dont shoot lasers, so a camera is good enough". But the implied reason is cost for sure. With how fast the price of lidar drops, and its abilities increase (think solid state lidar), I wonder how long until first tesla with lidar rolls down the production line, or if Elon is too proud to ever allow that
